Interesting discussion of the shortcomings of the P-400.
Two of the four pilots shot down returned to base and two others, Keith W Wythes and Robert E Chilson were missing. There was an after-the-fact MACR 601 recorded for the loss which discusses both men. The MACR was done because of inquiries by Chilson's wife. No serial numbers are given in the MACR. One of the men may have been captured by the Japanese, but there was no indication as to which man. Both were declared DED.
